About
This clump-forming perennial to about 1.5m in height, with a goblet-shaped habit and narrow, lance-shaped green foliage which turns to burgundy-red in the autumn. Masses of pale lilac-purple daisy-like flowers with a burgundy-red centre appear from late summer to autumn.
About the genus
Symphyotrichum includes around 90 species of annuals, biennials and perennials, mostly spread through the Americas, that were formerly included within the genus Aster. Leaves are simple, lance-shaped and entire, but it is their daisy-like flowerheads that they are grown for; central disc florets are typically yellow, surrounded by strap-shaped ray florets in shades of pink, blue, purple or white
